In 17th Century Europe, coffee beans imported from Ethiopia stimulated a new forum, coffee houses, for exchanging ideas on science and commerce with impacts that can still be felt today.

With COVID-19 our opportunities for one-to-one communication have been dramatically curtailed, but this disruption has provoked wireless communication spanning the globe.
